SRU justification:
Impact: As we were "asked" to go ahead and get a very recent thinkpad-acpi
driver enabled in Lucid, which exports an alsa mixer for the hw mixer that only
exists for ThinkPads. we now have a problem when people with TPs are asked to
try the latest ALSA from LBM. After installing LBM-alsa the thinkpad-acpi module
refuses to load as it wants the other symbol versions from the kernel.
Fix: I don't know of any better way than to put the thinkpad-acpi driver as it
is in Lucid into LBM and build it against the LBM-alsa core. It is then thrown
into the alsa package which mixes things a bit but I did not want to create a
new package for that.
Testcase: Verified that after installing lbm-alsa before caused thinkpad-acpi
not to be loaded. With the new version this works (and at least the wireless
card in that machine also still works with lbm-wireless installed.

As discussed, the stable team will have to be aware that any stable
updates or CVEs applicable to the mainline driver will also have to be
applied to the LBM version lest we cause regressions or leave security
vulnerabilities (a relatively remote possibility).

Looks good; will allow thinkpads to use l-b-m without breaking stuff.
